In fact, data localization is an issue that's being discussed in TISA. That work is not complete, but Canada's approach, which is shared by a good number of other participants, is to have a balanced approach so that we can still ensure a cross-border flow of data and at the same time protect the information that's held by government or in a government procurement context, so the two cases that you referred to, Nova Scotia and B.C., would not be part of TISA.
